During Hillary Clinton‘s trip to Las Vegas for Tuesday’s democratic presidential debate, she popped up at a labor protest outside of the Donald Trump International Hotel.

On Monday, the Culinary Workers Union Local 226 rallied to advocate for workers at the hotel to create and be part of a union.

According to the Huffington Post, protesters were surprised by Clinton’s appearance and expected one of the other Democratic candidates to arrive.

“It has to be Bernie,” said one woman, who referred to Sen. Bernie Sanders.

Clinton addressed the crowd:

“You have to say…’no’ to efforts to prevent you from organizing, to prevent you from having the kind of working conditions you deserve, the kind of wages that are going to give you a living wage. And that means saying no to Donald Trump.”

“Some people think Mr. Trump is entertaining. But I don’t think it’s entertaining when somebody insults immigrants, insults women. That is just unacceptable behavior. When we’re here together in solidarity to organize, we also want to send a message to Mr. Trump: That if you’re going to run for president, then you should represent all the people of the United States, and that includes hard-working people.”

In accordance with Clinton’s message, protesters continued to chant in solidarity for their right to demand proper benefits while employed by the Republican presidential candidate.
